GAS-MACHINE.

SPECIFICATION forming part of Letters Patent No. 321,959, dated July 14, 1885. Application filedOetober 1, 1884. (No model.)

To all whom it may concern.-

Be it known that I, AARON W. FRAIL, a citizen of the United States, residing at Ashland, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Gas-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, and in which- Figure l is a side view of my improved gasmachine, a portion of the casing being broken away to show more clearly the central part of the machine. Fig. 2 is a cross-section taken at line a a, Fig. 1, looking in the direction of arrow a, same figure. Fig. 3 is a horizontal section taken on line b b, looking in the direction of arrow b,same figure. Fig. 4 is a View of the under side of the top part of the case of the machine, showing the partitions or divisions between which the gas passes in its escape from the generating-wheel to the supply-pipe, in

.order to free itself from any particles of the liquid gasoline with which it may be overcharged by condensation. Fig. 5 represents, on an enlarged scale, a longitudinal central section of the machine, showing the several parts in their relative positions, and'Fig. 6 represents, on a smaller scale, a cross-section of the top part of the machine, taken on line 0 c, Fig. 3, looking in the direction of arrow 0, same figure, showing the inlet-pipe for the liquid gasoline and the valve mechanism for regulating the supply thereof.

My invention relates to improvements in machines for the production of illuminatinggas from liquid hydrocarbon; and it consists in certain novel features of construction and novel arrangement of parts, as hereinafter described and claimed.

In the drawings, A is the case of the machine for containing the several parts. It is made air-tight and of any suitable material and size.

In the top part of the case A is formed a shallow pan, B, for containing a supply of gasoline,which runs into the pan through the inlet-pipe (Z, (see Fig. 6,) the flow of the liquid being regulated by a valve, 0, and suitable mechanism for operating the same, consisting of a pivoted arm, f, and ball-float g of the usual construction, said float g resting upon.

the liquid gasoline contained in case A, as shown in Fig. 5, and being operated in the usual and well-known way. From the pan B the gasoline runs through an opening, h, therein, (see Figs. 8 and 5,) upon the generating-wheel,and into the lower part of the case A, the amount of gasoline being regulated by the float 9, before mentioned. The cover or top part, 'i,of the case A is provided with partitions or divisions as shown in Fig. 4, ex-

tending down therefrom at right angles, the

lower edges of the partitions j extending into the liquid contained in the pan B. (See Fig. 5.) The object and purpose of these partitions] is to form a circuitous passage (see arrows Fig. 4) for the escape of the gas after it has been generated and escaped through the opening h in the pan l3, and before it passes off through the supply-pipe 7.; in. the top of the case A, the object being to separate any liquid particles with which the gas may be impregnated or overcharged, said particles dropping into the pan B, and being used over again with the rest of the gasoline.

The generating-wheel O is made of two perforated or gauze cylinders, D and E,one with in the other, the outer cylinder, D,being provided with buckets or troughs l, for raising the liquid gasoline contained in the case A, and dropping it upon the inner cylinder, E. The wheel 0 is secured to and revolves with the shaft F, which turns in suitable bearings, m,made in one end of the case A, and in a re cess formed in one side of the part G, to be hereinafter described. (See Fig. 5.) The ends of the generating-wheel O are made solid, the end toward the part Gbeing cutout in the central part around the shaft F,and the cylindrical part a, open at one end and provided with holes 0 at the other end, is fitted therein and secured thereto, extending within the inner cylinder, E, about half the depth or Width of the wheel 0. (See Fig. 5.)

than the part a of the wheel 0, so as to allow the wheel. 0 to revolve freely around it, as shown in Fig. 5.

The driving-wheel J is constructed in the usual and well-known manner, of tin or other suitable material, and similar to wheels for measuring gas in wet meters. It is attached to and revolves with the shaft .K, which turns in suitable bearings, p,made in one end of the case A and in one side of the part G. (See Fig. 5.) On one end of the shaft K is secured a small gear, g, which meshes with a gear, 1, secured to the shaft F of the generating-wheel G, to turn said wheel. The end 3 of the drivingwheel J is made solid, provided only with an opening,through which the air enters, passing through the part G, one side of which has a projecting part, L, extending within said wheel, as shown in Fig. The other end, i, of the driving-wheel J is provided with flaring slots or openings, through which the air escapes after having acted on the wheel to turn the same.

Thepart or pipe G,before mentioned, is made of any suit-able material, of substantially the form and construction shown in the drawings, being secured in the central part of the case A in any suitable manner in the position shown. To one end of the part G is attached the inlet-pipe M, extending through the side of the case A, and through which the air is forced by means of any suitable blower outside of the case A. To the other end of the part G is attached the outlet or waste pipe N, extending through the side of case A, and provided with a faucet, from which the moisture condensed from the air may be drawn off. The part G has projecting from one side the hollow part L, before mentioned,which extends into the driving-wheel J, and around which said wheel revolves. Said part L has an arm or pipe, L, projecting at right angles therefrom, through which the air passes to the interior of the driving-wheel J.

Through the central part of the arm L extends a hollow air-tight slceve,(), (see Fig. 5,) secured to the part G, through which the shaft K of the driving-wheel J extends, the object of which is to allow the air to enter freely all around the part 0, inclosing the shaft K. The part G- has a depression, n, in one side, into which fit the gears q and 0', before mentioned, and also forming hearings in and p, in which one end of the shafts F and K turns.

The special object and purpose of the part or pipe G is to form suitable bearings for one end of the shafts of the driving-wheel and the generatingwhcel, the other end having bearings in the inner sides of the case A, as shown, and also to furnish in the best manner possible a means for the air to enter into the machine for the purpose of operating or putting in motion the driving-wheel,and also for becoming impregnated or charged with the gasoline in the generating cylinder or wheel.

The drivingwheel J and the part G, and the parts connected therewith, are incloscd in a separate case formed by the partition or top P and the side partition, I, which has formed thereon the cylindrical part H, before men tioned,whic h extends into one end of the gen crating-wheel G. The partitions P and I are secured within the case A in any suitable manner. The partition I does not extend quite to the bottom of case A, (see Fig. 5,) so as to allow the gasoline to circulate freely in the lower part of case A.

The object of inclosing the driving-wheel J and the part G, as above described, is to retain the air and allow it to escape and pass to the generating wheel or cylinder only in the direction as shown by arrows, Fig. 5.

The operation of my machine is as follows: The gasoline is first allowed to run into the lower part of the case A, through the inletpipe (Z and the opening it in the pan B, until the case A is about half full, as shown by dotted line m, Fig. The valve e,with which the inlet-pipe d is provided, is then closed by the raising of the float g, and as the gasoline is used in the manufacture of the gas, the lowering or sinking of the float 9 opens the valve in the usual manner, allowing more gasoline to run in. The pan B always has gasoline in it up to the top of the opening 71, as shown by dotted line y, Fig. 5. The driving-wheel. F, when it is desired to put the machine in operation, is revolved by forcing air by means of any suitable blower into the inlet-pipe M, through the hollow part G, part L, and part L, into the wheel J. (See arrows, Fig. 5.) The revolving of the wheel J causes the gcncrating-wheel O to revolve, the outer cylinder of which, D, being provided with troughs or buckets Z, as before stated, raises the gasoline contained in case A, and as the generatingwheel revolves this gasoline thus raised is poured out of the buckets Z and falls back upon the inner perforated cylinder, E, which cylinder being hollow,without any packing or absorbent material contained therein, a mist or spray of gasoline is formed within the inner cylinder, E,which is taken up by the air passing from the driving-whecl J, as shown by arrows, Fig. 5, into the interior of said cylinder and the generating-wheel C through the part H, and the holes 0 in the part a of one end of said generating-wheel C. The air, after being impregnated or charged with gasoline within the generating-wheel O in the manner above described, passes out through the perforated cylinders D and E, and through the opening h in the pan B, and between the partitions or divisions j in the top part of the case A into the gas-supply pipe in the top of case A, being evenly and perfectly carbureted before passing into said supply-pipe.

Having described my improvements in gas machines, what I claim therein as new and of my invention, and desire to secure by Letters Patent, is-

1. The combination,with the case A, perforated generating-cylinders D and E, and the driving-wheel J, ofthe tubular part or pipe G, for the purpose stated, all constructed and operated substantially as shown and described.

2. The combination, with the case A, provided with a pan, B, the top part of the case 5 A having the partitions or divisions j, of the perforated cylinders D and E, tubular part G, and driving-wheel J, all constructed and operated substantially as and for the purpose stated.

3. In a gas-machine, the part G, provided 10 with an inlet-pipe, M, and an outlet-pipe, N, for the purpose stated, and constructed with bearings for one end of driving-shafts, as described, and made hollow to allow of the air passing through into the driving-wheel, for the I 5 purpose stated, in combination with the driving-wheel J and perforated cylinders D and E, substantially as shown, and for the purpose stated.

4. In a gas-machine, the generating-wheel 0, made of two perforated or gauze cylinders, 20 D and E, the outer one being provided with lifting troughs or buckets, for the purpose stated, and means for revolving said generating-wheel, substantially as described, in combination with the tubularpart G and driving- 25 wheel J, substantially as shown and described.
